According to the US Agricultural Research Service more than a third of America’s commercial honeybees did not survive the winter. Jeffrey Pettis of ARS says, “We believe that some subtle interactions between nutrition, pesticide exposure and other stressors are converging to kill colonies.”
Here’s something I wrote two years ago: The Demise of the American Honeybee.
We lost both our hives last year. The first was driven off by wax moths, which was probably my fault for not having spotted them, but something had weakened the hive to make it unable to resist them. I have no idea what killed the second hive.
The first swarmed away and I’ve seen some honeybees in the corn this year, though far less than in the past.
Hopefully we’ll reintroduce bees onto our farm next year. If there are any left.
